This is the mature and responsible way to be a consumer. Understand the vendor's policies and make an informed decision based on them.I won't buy from them because of their return policy, sometimes because of my job two days isn't enough.
They may offer great prices and shipping but the policy on returns and defect is to tight.
The immature and irresponsible way to be a consumer is to whine and cry on the Internet when a vendor sticks to its guns and refuses to bend over backwards in order to protect its low pricing for the mature and responsible consumers.
